I just purchased a Huion KAMVAS Pro 13 GT-133. I realize it's not explicitly supported, but I thought I would post in case someone else has workaround.

Tried reinstalling latest driver and changing available settings, but it didn't help. If I open BlackInk the mouse works fine, but as soon as I start drawing with the tablet it stops displaying anything on the screen (just the white background on the page), whether from the tablet or the mouse.

:x if you have two butons on your pen try to configure the first so it can invert between the brush and the eraser. I dont know why but black-ink starts with the eraser on my tablet . I have a Huion GT156HD-v2

Sorry for the delay. Both ideas did not work unfortunately. I did try calibrating the tablet in Black Ink. Already did so in the Huion app. Ether way, I can click on anything in the UI but not the canvas/layers. The cursor is there, but nothing is painting with the stylus or even the mouse.

I have contacted Huion but no more answer for now What happen if you only use the mouse from the start ( do not move with your stylus ). Is it possible to draw something ?What happen if you press the E shortcut with painting with the mouse ?

Okay, after messing with the Huion panel for a while I got the secondary button to switch between brush and eraser like was posted earlier. It seems to be stuck in eraser mode like was posted, when first used.

This is strange also. Even though I was able to get it to work by switching from eraser to brush, the preferences window input preview show no pressure signal. But it appears to be working nonetheless. I see a signal on the azimuth and tilt though. Also, precise cursor position has to be turned off also to show any painting on the screen.
